Neck pain is very common. Chiropractors have been using manipulation (physical manoeuvres to mobilise bones in the neck and back) for many years to help alleviate symptoms of back pain. Numerous studies have proven that manipulation for neck pain works however it has never been compared against medicine (i.e. taking painkillers) or exercise as a treatment for neck pain.
A new study out this month does just that! You can read all about it here http://www.annals.org/content/156/1_Part_1/I-30.full where the study is explained in simple terms so it makes sense for patients.
